I have a situation that has repeated itself a few times. Someone calls into Asterisk and is connected with a voice extension. At some point during the call, the log shows "chan_zap.c: DTMF digit: f on Zap/2-1". At this point, the call is redirected to receive a fax and the Asterisk voice extension is hung up. The users report that there were no noticable tones heard just before the

Hi all, I have a simple and maybe also stupid question: if i'm in coversation on a Zap channel and the remote party send me a DTMF, could I capture it?

hi, exten =>6000,1,dial(SIP/6000,15,tr) exten =>6002,1,dial(SIP/6002,15,tr) exten =>6004,1,dial(SIP/6004,15,tr) exten =>6006,1,dial(SIP/6006,15,tr) exten =>6008,1,chanspy(SIP/6006 | wbq) when i dial 6008 ,it is connected ,but i can't able to hear the voice of the any one. when coversation between the 6002 to 6006. in my Console mode i got the following comment *CLI>

This bleed-over should not be possible with the CELT layer (_especially_ not during silence), but it is possible with the SILK layer. 1.1 added automatic speech

Correct. Another effect I forgot to mention is that Using FEC will actually force SILK/hybrid rather than CELT, so it's possible that disabling FEC makes you use CELT, which

Hi All, I'm struggling with an intermittent crosstalk issue resulting in a caller's audio being broadcasted to other calls (only one way as they are unable to hear the others listening in). Doing do diligence I've scoured the web in hopes of triaging the issue. So my thoughts are leaning towards this NOT being an Asterisk issue, but instead being related to the telco (PRI)

Hi, One other question I was wondering about. Is the reason that we hear the crosstalk with fec and packet loss percentage>0 is that Opus uses information from the left channel to try to error correct the right channel and vice versa? I am trying to understand the origin of the crosstalk. Thanks. -Jon > On Jan 27, 2017, at 12:29 PM, Jon Lederman <jon at soniccloud.com> wrote: >

Hi, Has anyone ever experienced crosstalk with sangoma analogue cards on 64bit? We have exhausted every test to try and replicate this and find a solution with Sangoma tech support, but we can not fix it. We are about to try the card and four *seperate* UK BT lines in a 32bit system. The current system is a 4gb, dual core cpu with pbx in a flash 1.4, Zaptel and Asterisk 1.4.21-2 Currently we

Thanks. When you say that with fec enabled, the threshold is increased, do you mean the bitrate - i.e., you need higher bitrate with fec enabled to suppress crosstalk? Also, can you make any recommendations to decide whether to use fec or not? We are trying to tune the parameters appropriately. Audio quality and reduction of crosstalk are critical for us. Thanks again. Jon Sent from my

Hi all, I am trying to set up a simple path analysis in the SEM package, but I am having some trouble. I keep getting the following error message or something similar with my model, and I'm not sure what I'm doing wrong: Error in solve.default(C) : system is computationally singular: reciprocal condition number = 2.2449e-20 In addition: Warning message: In sem.default(ram = ram, S = S,

Hello All, I''m new to the list and to Ruby. I was trying to use one of the examples as a skeleton for something that I''m working on. I''m currently stuck when it comes to adding another item to the sub-menus. I have a menu item by the name of "Tools" and I would like to add a sub-menu item called "Find Unique Fields" but it doesn''t show up

Stereo makes two assumptions: 1) It assumes the two channels are somehow correlated 2) It assumes the two channels are meant to be

I'm using samba 2.2.3a as fileserver and domaincontroller for 12 NT4-clients (sp6a) and occassionally - when a user tries to logon - there comes the following messages on the nt-client: - No Windows NT Domain Controller is available for domain XXXX. There are currently no logonservers available to service the logonrequest. - and - server-side profile not available. The OS tries to log you on

Hi, I have a dataset that I am trying to analyze and plot as an ordered logistic regression (y = ordinal categories 1-3, x = continuous variable with values 3-9). First is a problem with cdplot: Produces a beautiful plot, with the "right" trend, but my independent factor values are transformed. The factor has values from 3-9, but the plot produces an x-axis with values from 20-140.

Hi Am noticing smbd processes are running as root and occassionally I see a child process as userid Just curios under what circumstances the smbd runs as user id process ( unix id ) and running as root is a security risk? Thanks in advance -Abdul

I''m currently trying to optimize a linux machine which acts as a Layer 3 router of RTP H.263 video. Occassionally I''ll get delays related to layer 2 wireless retries, thus rendering the video on the recieving end stale/useless. Is there way to optimize a linux machine to route realtime video? In my case, losing a few frames of H.263 is better than having the video delayed

Hi, I`m occassionally seeing CDR(accountcode)'s value empty at a place in my diaplan where it was filled with some value a few lines before, with nothing else having changed it. It`s giving me headaches (as I rely on it for MySQL queries). Anything I can do? Mick -------------- next part -------------- An HTML attachment was scrubbed... URL:
